tikz-qtree – Use existing qtree syntax for trees in TikZ

The pack­age pro­vides a macro for draw­ing trees with
TikZ us­ing the easy syn­tax of Alexis
Dim­i­tri­adis’ Qtree. It im­proves
on TikZ’s stan­dard tree-draw­ing fa­cil­ity by lay­ing out
tree nodes with­out col­li­sions; it im­proves on Qtree by adding lots
of fea­tures from TikZ (for ex­am­ple, edge la­bels, ar­rows be­tween
nodes); and it im­proves on
pst-qtree in be­ing us­able with
pdfTeX and X∃TeX.
